general problems of the 1996 Mazda Protege

My 1996 Mazda Protege lx (1. 5 liter engine) suffers from such extreme engine vibration that the car has recently become practically undriveable despite its low mileage of 83,000k and a good maintenance history. The car shakes severely when starting, jerks severely when shifting gears and is surging almost uncontrollably at various times. It is unsafe and I have been told that all engine mounts must be replaced at this time. In looking at the vechicle history, there has been manufacturer service bulletins about excessive engine vibration. I believe this to be a significant manufacturer defect that causes unsafe conditions and undue burden and expense to consumers. The estimate future expense to me is close to $1,000. 00.
